OP-TEE provides a pseudo TA to enumerate TAs which can act as devices/
services for TEE bus. So implement device enumeration using invoke
function: PTA_CMD_GET_DEVICES provided by pseudo TA to fetch array of
device UUIDs. Also register these enumerated devices with TEE bus as
"optee-clntX" device.
On ARM SoC's with TrustZone enabled, peripherals like entropy sources
might not be accessible to normal world (linux in this case) and rather
accessible to secure world (OP-TEE in this case) only. So this driver
aims to provides a generic interface to OP-TEE based random number
generator service.
This series introduces a generic TEE bus driver concept for TEE based
kernel drivers which would like to communicate with TEE based devices/
services.
Patch #1 adds TEE bus concept where devices/services are identified via
Universally Unique Identifier (UUID) and drivers register a table of
device
This flag indicates that requests in this context should not wait for
tee-supplicant daemon to be started if not present and just return
with an error code. It is needed for requests which should be
non-blocking in nature like ones arising from TEE based kernel drivers
or any in kernel api that use
Introduce a generic TEE bus driver concept for TEE based kernel drivers
which would like to communicate with TEE based devices/services. Also
add support in module device table for these new TEE based devices.
In this TEE bus concept, devices/services are identified via Universally
Unique Identifi

Hi Horia,
I didn't understand your patch thoroughly yet, but I tested it and it
